From: Geliang Tang <tanggeliang@kylinos.cn>

Use local helper make_client() in run_multi_prog_lookup() instead of using
make_socket() + connect(). Then make_socket() and inetaddr_len() can be
dropped now.

make_client() returns normal "fd" instead of "-1" when connect() fails
but "expect_errno" matched in it. So "err = -errno" is needed to get the
real error number before checking value of "err".
